The code that initializes cpus on arm64 is currently split in two different code paths that carry out DT and ACPI cpus initialization. Most of the code executing SMP initialization is common and should be merged to reduce discrepancies between ACPI and DT initialization and to have code initializing cpus in a single common place in the kernel. This patch refactors arm64 SMP cpus initialization code to merge ACPI and DT boot paths in a common file and to create sanity checks that can be reused by both boot methods. Current code assumes PSCI is the only available boot method when arm64 boots with ACPI; this can be easily extended if/when the ACPI parking protocol is merged into the kernel.
